Looking for Ten SCTE Tips

Just ordered the truck the other night and I am going to take my first run at brushless. I have been into R/C for awhile but got out of it before the all the new brushless equipment came out and was mainstreamed. Now I have been seeing alot of people running alot of different things. i think i am going to go the 550 route due to cooler engine temps, a little more torque and have more longevity from the motor. Looking to see what some opinions are out there or some advice on systems you guys have used yourself and seem to be proven. Also any other tips or advice would be appreciated. As of right now I know the diffs come greased instead of oiled so i plan to do that right away but would like some more insight on other tips or tricks. Let me know what you guys think.
Thanks

Ordered up the Rx8 and 4.5T motor along with FTW carbon shock towers and a FTW motor fan kit. looks really clean, should have my stuff by next week. Ill post up some pics and let you guys know how it goes im really stoked to run this setup
